Concept art for vehicle designs

Currently, I have been continuing making some silhouette designs for vehicles within Photoshop. The first part involved me grabbing some silhouette designs off of the internet then opening them up within Photoshop then taking apart different sections of the vehicles and mixing them together.

The second part involved me just making random scribbles with the lasso tool to make a random design then filling it with the paint bucket then using the paint brush tool to fill in the gaps and create a full silhouette design as well as improve some sections that may have looked a bit off when it was initially filled with the bucket.
